A flask containing `12 g` of a gas relative molecular mass `120 at` a pressure of `100 atm` was evacuated by means of a pump until the pressure was `0.01 atm`. Which of the following in the best estimate of the number of molecules left in the flask `(N_(0)=6xx10^(23)mol^(-1))`?

Options

A. `6xx10^(9)`
B. `6xx10^(18)`
C. `6xx10^(17)`
D. `6xx10^(13)`

Explanation

To solve the problem, we will use the Ideal Gas Law and the relationship between pressure and the number of moles of gas. Here is the step-by-step solution:

### Step 1: Understand the Ideal Gas Law
The Ideal Gas Law is given by the equation:
\[ PV = nRT \]
where:
- \( P \) = pressure
- \( V \) = volume
